7 '0 all whom it may. concern:

Be it known that I, CARLETON ELLIS, a citizen of the United States,residing at Montclair, in the county of Essex and State of New. Jersey,have invented certain new and useful Improvements in Cloth-TintingCompositions and Processes of Tinting Cloth, of which the following is aspecification. I

This invention relates to a process of treating the lining of automobiletops and relates especially to a method of spraying a tintingcomposition on such linings and to a composition' adaptedfor suchtinting par-- 15- oses. tp The invention is concerned especially withthe revival or renewal of the linings of automobile tops such as theordinary touring car top which has an outer fabric of leather or leathersubstitute and an inner lining of cloth which is usually looselyattached to the outer covering. The inner cloth lining very quicklybecomes weather stained and streaked from water and dust and becomesunsightly. While the outer fabric may be treated with leather dressingsto restore its appearance, heretofore there has been no satisfactory wayof reviving the interior or lining.

Accordin to the present invention, inits preferred orm, a solution ismade in a h drocarbon solvent of a dye which is solu le in such solventbut insoluble in water.

' The oil soluble dyes now on the market and used in varnish stains maybe employed for the purpose. They are sold under various names and arereadily obtainable. Ordinarily I prefer to use a stain which gives abrown, drabor mahogany tint. It is desirable to have the solution strongenough in dye to adequately cover the water stains of the fabric. It isalso desirable to have resent a small amount of resin to better old thedye in place and to serve to slightly un esirable to use a heavy bodiedvarnish basis or an hing of this description because it ren ers thefabric stiff and also may Specification of Letters Patent.

brighten the fabric. On the other hand it is.

2% and 8% satisfactory results are obtained. The resin is calculated onthe weight of solvent employed. The resin also serves to some extent asa Waterproofing agent so that when cloth so treated is again exposed torain water stains do not form as readily.

A suitable solvent vehicle is benzol or toluol but preferably varnishpainters naph the or heavy benzine is used. 'A mixture of benzine andbenzol may be employed.

The proportion of the oil-soluble color may be approximately one percent but may vary more'or less according to the intensity of the tintdesired.

A suitable composition is made by dissolving 2% 'of cumaron resin in asolvent composed of 90% of varnish makers naphtha and 10% of benzol andadding a mixture of one part of oil-soluble orange stain to two parts ofoil-soluble oak stain, the proportion of oil-soluble dye in this case isone gives-a brownish tone with per cent. This a slightly reddish tintwhich quite effectively covers the weather stains on the fabric.

If such a composition were'applied' with a brush it would be diflicultto make even application but by. means of spraying the composition maybe applied uniformly. However if a sprayer does not work properly anddrops of the composition fall on the fabric the resulting blot isdifficult to cover by subsequent coats of the composition as applied byspraying.

However I the spray to-the cloth from the underside when' the cloth isin a horizontal position as for example inits normal position in theau-' tomobile top.

One feature of the invention therefore is that of spraying a compositionof this character in a substantially vertical position against thefabric thereby overcoming the danger of not securing a uniform-applica-' find that it is possible to apply tion. Hence it ispossible'to treat-the fabric from the machine.

Other resins or binders such as shellac, ordinary rosin, rosin ester anddrying oils such as linseed oil, wood oil, etc., may likewise be' usedin some cases. However a resin which-is substantially unafi'ected bywater, that is does not turn white or change in the automobile topwithout its removal. 9

in appearance on contact with water is pr'eferre Othermixtures may-beused. which have a.

water-proofing effect as for example a solution of paraflin or betterceresin wax in benzol or toluol. This is tinted with the oil solubledye. 2 or 3% of wax sufiices to'secure desirable waterproofing resultsbut the wax may be increased if desired. Non-inflammable solvents suchas trichlorethylene.

or carbon tetrachloride may be used.

Ordinarily a quick drying composition is desired as the fabric ispreferably quite thoroughly wetted with the solution and with slowdrying materials present the liiring would require a rotracted exposurein order to render the fa ric perfectly dry. By the use of smallquantities of resin in this manner a binding effect may be securedwithout the employment of drying o'il.

Other solutions such as alcoholic solutions of dyestufl's which areinsoluble in water may likewise be employed but as a. rule do not giveas satisactory results. It is also possible to spray a water'soluble dyeas for example an aqueoussolution of a dyestufi' on the fabric and subseuently treatwith a mordant or fixative. owever the present emma processinvolving the use of a dilute resin solution containing an oil solublebut waterinsoluble dyestuff and sprayed vertically against the fabricaccomplishes very satisfactory results at a low cost and with asimplicity of operation which is desirable. The top does not have to beremoved from the body of the car in order to treat it. This preferredmethod therefore is recommended
